Is Zinc Oxide Natural?

Q: Is Zinc Oxide natural?

Zinc Oxide has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. Zinc oxide is primarily produced through the direct oxidation of metallic zinc, which is derived from zinc ores, classifying it as 100% petroleum-derived based on the origin of … An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.
